To all whom it may concern V Beit known that I, HANS K. LORENTZEN, asubject of the King ofDe'nmar-k, and resident of the city, county, andState of New York, have invented-anew andusefuli Apparatus forlllanufacturing. Horseshoes of which the followingfisa specification.

In manufacturing horseshoes it is necessary'to makeseveralsizesof diesfor differont animals and inaddition theretoit is necessary to makeshoes of diiferent sizes fori the same animals;- that is, shoes-made forthe fore feet of a horse are not suitable for the hind feet of the sameanimal because-the I latter must be slightly narrower and longerthanthose for the fore'feet. Heretofore it? has been customarytomanufacture various sizes for different'animals and to separatelymanufacture the fore andhind-shoes When the shoes are made by a dropforgingprocess it isnecessary to'ha've a greatmany dies which are notonly very costly in the first instance but'their life is very short-asit is almost impossibleto manufacture more than from five .to tenthousand-shoes from a sin- I gle die before the latter becomes worn out.w

The object of my present invention is to make it possible to form bothfore and bind shoes from the same die or set of dies. I

In addition thereto-my object is to make f it possible to carry instocka smaller number of shoes.

My invention also relates to a novel die; for convertingthe shoes,which'die has a tapered opening thr-ough*which horseshoes are 3 adaptedto be driven for' the purpose of transforming fore shoes intohind shoes;

In the drawings forming a part of this applicatiom-Figure 1 is aplanviewof the die which forms a part of my invention. Fig. '2 is a crosssectionthereof taken on-thel line2-2 of Fig.1, and Fig?) is alongi-i tudinalsection taken: on the. line 3-3- of.- ig- My improved die is suitablefor use'in a method which consists in manufacturing horseshoes of suchsha-perand'dimensions as will conform to the requirements for the forefeet of horses, preferably by any ordinary-drop forgemethod andafterward reforming or reshaping as many of the shoes may be necessaryto be used for hind shoes. For this purpose fore shoes of diiferentsizes for different classes of horses may be formed according to thestandard requirements and these shoes are somewhat wider and somewhatshorter than the shoes ordinarily'required for the hind feet. That is tosay, the .fore shoes are usually curved outwardly at apointjust beyondthe toe calks to a point near the heels of the shoes in a somewhatlargerarc than the hind shoe for the same animal; but the spread at theheel maybe and preferably is, the same for both fore and hind shoes.

I first form anumber of shoes of suitable size and dimensions for thefore feet and make the same of standard size, that is, I make shoesknown as 1, 2, 3, 4, 5, .etc., and then'after producing all of the shoesin the forging. dies Whichproduce shoes suitable for the fore feet Ipass a number of these shoesthrougha tapered'die for the purpose ofreshaping the same to make them conform to the requirements for hindshoes. 'Thislatter operation is very simple and ineXpensive'a-nd may beperformed after the shoes are, otherwise completely finished.

This' operation may be performed by the manufacturer previously toputting the shoes on the market or it may be performed by the jobber orwholesaler according to the proportion of fore and hind shoes required.for his particular sales. That is to say, if a ,dealer has a thousandsets of shoes in stock he is very apt to receive orders for a larger.percentage of fore shoes than hindshoes and it is possible, by keepingin stock only fore ,shoes and by converting only such propor- .tionoffore shoes into hind shoes as the sales may require, to supply theordinary demand from the smallest stock of shoes.

In the drawing forming'a partof this application I have shown a tapereddie. This the consists of a bed 1, adaptedto be bolted to any suitablesupport andextending up- ;wardly from this bed I have arranged a rec-.tangularflange consisting ofend members 2 and 3, and side members 4 and5, which serve to hold the several parts of the die in position. The bed1 is provided with an opening (5, in line with the opening-of the the,through. which shoes are adapted to be driven. The die itself isprovided with an opening 7, through which shoes are adapted to bedriven. This opening at the top 8, where the shoe 9, is inserted is soshaped and proportioned as to, conform to the contour, of a shoe formedin the proportion and shape of a fore shoe. The side walls 10, 11, ofthe die preferably between the points 12- and 13, gradually taperinwardly from the top of the opening 7 to the bottom 15, therei of, at14. This makes the bottom of the that as the shoe moves through the diethe 7 lengths I provide spacers 2 1, between the heel portions will bepressed against the block and will emerge from therdie the same distanceapart as when the shoe is first placed in the die. I have so constructedthe diethat it can be adjusted for different size shoes in order thatone die may serve for all. For this purpose I have constructed a die infour separate pieces 20, 21, 22, and 28, and in order to adjust the diefor shoes of different members 20, 28, and the members 22, 21. By

inserting more or less of these spacers the.

length of the die may be suitably arranged for shoes of differentlength. In orderto adjust the die for shoes of different widths Iprovide spacers 25, between the. members 21, 20, and the members 22, 23,and by providing one or more of these spacers of suitable thicknessbetween the die members the width of the opening of the die may bechanged for shoes of difierent width. I have provided screws 26, whichare threaded through the flange member 8, and are adapted to engageagainst the die members 20' and 21. 1' providesimilar screws 27,threaded through the flange member 2, which engage against the diemembers 22, and 23, and together with the screws 26, cooperate to retainthe die members in contact longitudinally of the die. I have providedscrews 28, which are threaded through thefiange member 5, in' contactwith the sides of the die members 20, 23. I have provided similarscrews29, which contact with the sides of the die members 21, 22. Bytightening the screws 28 and 29 the die members are firmly held togetherin the lat-- eral direction.

The shoes having been made to conform to the requirements for fore shoesany number or portion thereof may be converted into hind shoes byforcing them through this die. For this purpose the shoe is placedhorizontally in the opening at the top thereof with the heels 17 incontact with the wall 19, and the shoe will conform to the curvature ofthe top of the opening 7 The shoe is then driven through the die by anysuitable means and the inclination 10 of the side walls of the die willreduce the lateral dimensions of the shoe. At the sametim-e the walls19, will prevent the shoe from buckling by retaining the heels 17 inspaced relation and this action together with the action of the inclinedwalls 10 will cause the shoe to elongate as it passes through the die.The space 16 is to permit of this slightelongation. When the shoe passesthrough the die it will pass through the opening 6 in the bedi plate.When the shoe has been driven through the die it will conform to theshape suitable for use as a hind shoe and will be in condition to besold as such without further treatment. Regardless of the method bywhich the shoes are first formed this operation simplifies themanufacture of the shoes because all of the shoes'of a given size may befirst formed as fore shoes and afterward a portion thereof may bereshaped into hind shoes. It is particularly advantageous where shoesare made by a drop forging method. 1

Having described my invention, what I claim is;

1. A die having an opening through which a'horse shoe is adapted to bepassed, said opening being defined by slanting side walls for thepurpose set forth, and a spacing block adapted to cooperate with theheel portions of the shoe for the purpose of preventing a buckling ofthe shoe while the latter is reduced in its lateral dimensions by theinclined walls.

2. 'A die for the purpose set forth compris ing a plurality of separabledie members, spacers for the said die members adapted to retain the diemembers in spaced relation, said die members having an opening for thepassage therethrough of a horse shoe, said '22, 23, said members 22 and23 having separating blocks 18, separators for spacing said die members,one of which is adapted to separate the members 18, said die membershaving an opening for the passage therethrough of a horse shoe, theWalls of said opening being inclined for the purpose set forth, saidincline extending from points near the front of the shoe to points nearthe ends thereof, and of gradual increasing extent between said point-s.
